RT9080N-18GJ5

The RT9080N-18GJ5 from Richtek is a 600mA low dropout (LDO) linear regulator with SNS (output voltage sense) pin in 5 pin TSOT-23 package. This regulator with enable function operates from 1.2V to 5.5V. It provides up to 600mA of output current and offers low power operation in miniaturized packaging. The features of low quiescent current as low as 2μA and almost zero disable current is ideal for powering the battery equipment to a longer service life. The RT9080N is stable with the ceramic output capacitor over its wide input range from 1.2V to 5.5V and the entire range of output load current (0mA to 600mA). The minimum required output capacitance for stable operation is 1μF effective capacitance after consideration of the temperature and voltage coefficient of the capacitor. Because of the small input current at the SNS pin, the RT9080N with SNS pin also can work as an adjustable output voltage LDO.
